For years, I kept hoping that the President and Congress would do something to rein in the corporate media companies who continue to showcase hatemongering radio and TV commentators, and rake in millions of dollars at the expense of reasoned debate and civil public discourse. I wrote letters about my concerns to my congressional representatives. I blogged about it. I wanted our public officials to take this abuse of free speech on our public airwaves much more seriously.

I wasn’t as worried about President Obama’s safety, because of the fortress-like security apparatus afforded to American commanders-in-chief. No, I had a feeling that the first attempted political assassination of a government official in many years would be on a member of Congress. Now it’s happened. And so many other innocent lives were lost or ruined in the attack.

None of these extremist broadcast commentators told Loughner, or anybody else, to go and massacre people. But they and the companies who employ them have perpetuated an environment where violent rhetoric is deemed an acceptable form of entertainment, where media personalities steer close to or even commit incitement, and where alternative viewpoints are scarce. Unfortunately, our public leaders – Democrats as well as Republicans – have acquiesced to the wishes of Big Media by allowing deregulation and corporate consolidation. Our government has also gotten rid of equal time rules, and declawed the Federal Communications Commission, which is supposed to oversee broadcast outlets and protect the public interest. On top of that, the United States, unlike other Western countries, lacks a robust public broadcast system that can provide an antidote to corporate media’s worst programming. So we see large portions of the population whose only source of news and information comes from extremist radio figures and lightweight local TV news broadcasts. Add to this large-scale ignorance, a toxic brew of massive income inequality, racism and bigotry, and easy access to guns. It took Pima County Sheriff Clarence Dupnik, who oversees Tucson, to finally say to the mainstream what many of us in the media reform movement have been screaming about for years:

“When you look at unbalanced people, how they respond to the vitriol that comes out of certain mouths about tearing down the government,” he said. “The anger, the hatred, the bigotry that goes on this country is getting to be outrageous and unfortunately Arizona has become sort of the capital. We have become the Mecca for prejudice and bigotry.”

…

“It’s the vitriolic rhetoric that we hear day in and day out from people in the radio business and some people in the TV business. People tend to pooh-pooh this business about the vitriol that inflames American public opinion by the people who make a living off of that. That may be free speech but it’s not without consequences.”

Many are calling on the haters to tamp down the vitriol. Interestingly, Roger Ailes, CEO of Fox News, the cable network that is now synonymous with rightwing flamethrowing and propaganda, is asking “both sides” – meaning left and right – to tone it down. Other mainstream media outlets are also continuing to put out this false meme that liberals and conservatives are equally responsible for the venom polluting the public airwaves. Ailes and his ilk know perfectly well that it is conservative leaders, media pundits, TV and radio personalities who are primarily the ones spreading hate speech and violent rhetoric. Liberals just don’t have the kind of money or access to as many broadcast stations as do conservatives. And what liberals have said in public, while provocative, just doesn’t reach the same level of bloodthirstiness that we’ve seen from conservatives.

But the real point here is that no amount of pleading for calm will stop the behavior. There may be a pause for a while, but I doubt it will last. The media conglomerates are just making too much money from hate speech. That has to change. Unless and until laws with teeth are put back on the books to regulate the media companies, the invective will escalate and more tragedies will happen. What should be done?

Break up the media monopolies: There are only a handful of companies that control almost everything Americans see and hear. That means only a handful of executives (typically white and male) are dictating what kind of information is available to an increasingly diverse public. This also means that a handful of executives are using toxic radio and TV personalities to sow divisions among the citizenry just so they can try to sell us their corporate propaganda. That must end. Allowing Comcast and NBC Universal to merge is taking American media in the wrong direction.

Give the FCC and the public more enforcement power: When President Clinton signed the Telecommunications Act in 1996, the interval between renewing broadcast licenses increased from five to eight years. That should be reversed. (FCC Commissioner Michael Copps wants to reduce the period to four) In addition, broadcasters whose media personalities routinely incite violence and threaten people or groups with bodily harm should have their licenses revoked. In addition, it should be just as easy to file a challenge against a station for hate speech as it is for profane speech. We may have free speech rights, but no one has the right to own or broadcast on a radio or TV station. Broadcasting on our limited public airwaves is a privilege, and broadcasters must be held to certain standards.

The United States must implement an independent, 100%-taxpayer-funded public broadcasting system with TV and radio stations available in every community – urban and rural. PBS and NPR, with their paltry taxpayer subsidies and commercial underwriters, just don’t cut it. We need something on par with the BBC. This new public system must have access to frequencies equally as powerful as the ones available to commercial stations. Public broadcasting systems in other Western countries have a much more expansive array of high-quality produced shows featuring culture, politics, science and documentaries. Citizens in countries with robust public broadcasting systems are exposed to a wider variety of political views and are therefore, more informed than Americans. Toxic speech must be counteracted with more diverse and better speech.

All Americans deserve equal access to fast, affordable and high-quality broadband that is free of corporate manipulation and control.

Thanks to our First Amendment, Americans probably enjoy the most permissive free speech rights of any modern democracy. But this right is not absolute. Some are abusing the First Amendment by using the public’s airwaves to stir up hatred and division. They are profiting off the public trough and giving out only garbage in return. Extremist radio and TV commentators are not directly responsible for the political violence plaguing America today, but they have contributed to the creation of an environment of nastiness in our public discourse that can influence disturbed individuals like Jared Loughner. If this extremist speech isn’t soon ostracized from public life in the U.S., the lone, crazed gunman will morph into organized mobs hell bent on murdering political opponents and even committing genocide.

Last night, Rachel Maddow devoted her entire show to an interview with comedian and The Daily Show host Jon Stewart, who explained what he was trying to accomplish with last month’s Rally to Restore Sanity. The rally, which drew more than 200,000 people to the Washington Mall, was criticized by some for being a pointless exercise rather than a call for civic engagement. Comedian Bill Maher had taken issue with Stewart’s charge that liberals and conservatives are equally to blame for the incivility of American politics today. Stewart doubles down on this belief, and goes on to comment about the corrosive effect of the 24-hour cable news cycle has on our public discourse.

I don’t agree with everything Stewart says here, but he makes a lot of good points about the problems with cable news. Stewart views himself first and foremost as an entertainer, as he should be, not a news sage or political leader. I like The Daily Show as much as anyone, but too many people turn to it as their primary source of news, when they should be getting the information they need from real news organizations, who, for the most part, are falling down on the job of exposing official corruption.
